Blockchain-Based IoT Architecture for Software-Defined Networking

The most popular research advances in emerging technologies are software-defined networking (SDN) and blockchain technology (BCT). These systems have been used in the Internet of things (IoT) environment for various purposes, such as security, reliability, interoperability, privacy, and so on. In this respect, such strategies can be used to efficiently include cloud storage with protection, confidentiality, and privacy. Privacy and power aspects play a significant role in the transferring of information through IoT due to the power and processing of restricted interconnected systems, that is, processing and storage resources. Whether fraudulent or unintentional, there are possible real-world effects of data intrusion in an IoT system. In this chapter, we discuss the potential to combine blockchain technology and software-defined networking (SDN) to alleviate some of the problems. Particularly, using cluster architecture with a modern routing protocol, we suggest a stable and energy-saving blockchain-enabled SDN architecture for IoT. The experimental results suggest that the cluster structure-based routing and packet-oriented routing have better latency, power, and rugged performance than the above routing protocols. The cluster structure-based routing protocol has improved performance than other routing protocols with respect to performance, power savings, and robustness. The cluster structure-based routing protocol has better sensitivity to packet loss. The cluster structure-based routing protocol has improved performance in the presence of foundering. The performance of the suggested architecture is justified based on the observation of simulation results with the choice of applicable parameters.
